HAND-THREADING SHUTTLE.

Specification of Letters Patent.

Patented Feb. 28, 191i Application filed September 13, 1909. Serial No. 517,395.

To all trhom it may concern:

Be it known that l, (inonor. M. CHENEY, a citizen o't tho-United States, and resident of Houthbridge, count ot' \Yoreester, State of bltlHSttt'llllSLllH,'ll:l\'t invented an improvement in llands'lhreading Shuttles, of which the following description. in connection with the accompanying drawing. is a specification, like characters on the drawing representing like parts.

This invention relates to looni shuttles,

and more particularly to that class. teehni cally termed halal-threading shuttles, wherein the thread of tilting is guided or directed to the delivery-eye of the shuttle by the hand ot'the weaver. and the invention has for its object the production of novel and etlicient nieans tor guiding and controlling the thread after the shuttle has been threaded; for facilitating the threading operation. and for siuiplitving and cheapeuing .the construction ot the device as a whole.

In the present embodiment ot my invention the thread is ledjfroni the cop or bobbin, in the usual lmbbin-reeess ot the shuttle. to

the point t i delivery at the shuttle side b v means o'l communicating thread passages, one o't' which receives the thread from the lmbbin-passage. while from the other the thread is delivered.

The thread is introduced into the passages in the threading operation by in ans ot' an open threading-slot. which comprises a vertieal slot leading 'lroni the top of the shuttl and au intersecting horizontal slot. and l have provided a novel toriu o't threadretainer to perntit the ready entrance o't the thread to the passages, while thereafter preventing its escape therel'roin.

The various novel leatures ol' nrv invention will be fully described in the suhjoined specification and particularly pointed out in the t'ollowing claims.

I have herein illustrated several tot-ins oil in) invention. var ving in certain l' 'atures of construction and arrangement. as will be reterred to and explained in detail hereinat'ter.

Fig. 11. looking toward the left.

My invention is applicable to any usual form of shuttle,as herein illustrated, the shuttle-body S having the usual recess S, Figs. 1, 2, t and 1t. tor the cop or bobbin S Fig. l.

In the present embodiment of in)- invention. see Figs. '1. to 5, and Figs. 9 and It). a transverse and preferably horizontal threadguiding passage 1 leads fl'Olll the front side wall of the shuttle inward to a point somewhat he vond the longitudinal axis at the. shuttle said passage being formed by a suitable boring tool. and as' the thread is delivered front the outer end of said passage l term it the deliveringpassage. Near its outer end said passage is interseeted by a vertical hole 2, bored into the shuttle wood from the bottom, and elearlvshown in Figs. and 5. A second thread-guiding passage is formed in the shuttle body. by borini ner end of the passage 1. and in the embodinient ot' the invention illustrated in Figs. 1' to 5 the passage .3 is carried upward above the. delivering passage. but cutting through the front wall at the reduced forward end S- ot" the bohbilrrecess, see Fig. 4'. .\s this thread passage 3 leads tron] the bobbin-1e eess and receives the thread 'l'roin the bobbin therein 1 terin it the receiving passage. the two thread passages 1 and 3 connnunieat'ing at'their inner ends, so that. the thread can pass from one to the other.

So far as described the operations upon 1 vertical hole therein intersecting the in-.

tl t) live means for retaining the thread in the with such introduction 'o'f les's width than the diamet'er of'the body,

annular edge.

the shuttle involve the use'of a simple boring tool, and can be performed readily and cheaply. I I In order to guide or lead the thread quickly and easily to the thread passages in l the manual threading operation provide an open threading-slot leading thereto, and comprising a vertical arcuate slot 4; cut in the top of the shuttle-body and extending from a point in the wall of the part S of the bobbin-recess forward andlaterally to the shuttle side, while a horizontal slot isinade in the shuttle, from its side inward. The slot t connects atits bottom with the horizontal slot 5, and the latter intersects the thread passage 1 at a slight distance-above its bottom, Figs. 3 and 5. The slot 4 intersects the vertical thread passage 3, as best shown in Fig. 5, so that communication therewith is effected.

y In the threading operation the weaver grasps the end of the filling thread 6, Fig. 1,

- the right position.

extending from the bobbin, and pulls it for- Ward and downward into the vertical slot 4 and then rearwardly into the horizontal slot A pull on the thread draws it downward into the vertical receiving passage and at the same time the thread passes therefrom and from the horizbntal slot 5 into the transverse thread passag 1, and the thread ing of the shuttle will be completed. As a matter of fact, however, the thread could escape from the thread passages almost as easily as it entered them, were not some retaining means provided to hold. the thread. in the passages.

,I have provided novel simple and efi'ecthread passages after it has been introduced thereinto, while not interfering in any way nor impeding the proper. draft of the thread as it is delivered from the, shuttle when the latter is picked.

Thethreadsretaining device for use in the transverse passage shown separately in FigfS, and it comprises atubular, cylindrical body'ti, preferably made of sheet or plate metal, bent or'pressed into shape, and surmountedby an overturned, hook-like head 7 with its free end or extremity 8 incurved or turned back and extended downward into the open upper end of the body below its I This headis practically a narrow tongue-like extensidn from the metal forming 'th e body, andwhen -bent over as shown it forms an eye having an entrance between the lower.face of the extremity 8 and. the adjacent edge of the body, which is t) to facilitate the entrance of the. thread into the head, The body '6 is of such external diameter that it enters with a driving fit ti vertical hole 22in the shuttle, and it is forced. thereinto head first until the head? enters and is substantially concentric to the thread passage 1, Fig. 5, the proper positioning of the head across the passage being facilitated by making a notch 10 in the lower end of the body, by means, of which a suitable tool can insert the device in the hole 2 and turn it to bring the 11 ad into exactly When so positioned the entrance to the head 7 is toward and adjacent the intersection of'slot with the passage 1., the upper edge of the body being flush with the bottom of said slot. so that when the thread is drawn back through the slot it is carried under the tip or extremity Q of the head and into the eye forme there by, the notch 9 facilitating such entrance. 01-169 the thread is within the eye or l'lOOklike head 7 it cannot escape therefrom for the upper edge of the body, over which the thread draws as it is delivered, holds it' up above the extremity 8. As the head 7 is located adjacent the outer end of the thread passage 1 it serves in )ractice as thedeliveryeve for the shuttle, as will be apparent. In the modified form shown in Figs. 9 'and 10 this same retaining device is used, in the manner described, and occupies the same position in the transverse passage 1, performing the functions ust set forth.

Returning now to the structure illustrated in Figs. 1 to 5, the retaining device for the receiving passage 3 is very similar to the de vice shown .in Fig. 8, but differing in the fact that the cylindrical, tubular body 11, Figs. (5 and 7, is provided with a longitudinal opening or slot 12, the hook-like head 13 surmounting' the body, as before, and its extremity 14 is turned'back and extends downward below the upper edge of thebody. The entrance to the head is opposite the slot 12,

whichis slightly beveled at one side, at 15,

Figs. 6 and 7, tofacilitate the entrance of the thread into the head. The body 11 is for ed upward through the passage 3 with its opening 12 opposite the intersection of the slot at .with the passage 3, see Fig. 5, and the bottom of the bodyiis slightly above the upper edge of the horizontal part 5 of the threading slot. As the thread is drawn down into the vertical slot lin the threading. operation t passes over the exposed part of the head 13 andnnder the extremity let into the eye formedby the head and thence through the longitudinal opening 12 into such body, and at the same time the thread draws under the lower edge ofsaid body into 'the transverse passagel and into the head? of the retaining device therein, as shown by the line t, Fi '1 5. The shuttle is nowacompletely'threaded, and escape of the thread from either of the thread passages 1 or 8 isprevented by the hook-like retaining devices 7 and 13, as wi'll be apparent. Should the thread loop and Be thrown forward from. the bobbin toward the threading'siot it cannot enter the latter, for

' thc pin but cannot pass ninlcrncath it.

the head 13 is hooked around the thread so that it.- cannot escape, and when tension is applied to the thread the loop is straightened out and disappears.

In Fig. l the dotted line 29* shows the thread as itis about, to be drawn back in the horizontal lot 5, while in full and dotted lines If the th cad is shown under the full control of tin retaining devices. The body' 11 not only holds its head 13 in fixed position but. it also.,,serves as a metallic lining for the parrot the thread passage 3 through which the thread draws, and as the thread is changed in direction from substantially a horizontalpath to a. vertical path, and then back to a horizontal path, a sufficient tension is put upon it to preventtoo free delivery.

Having reference to Figs. 9 and 10, the vertical hole or thread passage 3* which coininunicates with the transverse passage 1, as before, is bored from the bottom of the shuttle up into the part S" of the bobbin-recess at the inner end of the vertical part 4: of the threading-slot, and-a. metal tube 16 is forced up into the passage 3 flush with its upper end. Said tube has a longitudinal slot 17 which communicates with the slot l, so that in. threading the shuttle the thread is drawn down into such slot and passes thence, through the slot. 17 into the tribe ll), which serves a. lining tor the vertical thread passage 3* in the part thercoi traversed by the thread. To prevent. escape ol the thread theretrom I drive a pin l8 diagonally through the shuttle body from its rear wall .i'rontw-ard, the free. end o'l' said pin entering the open upper end oi the tube It with its tip or extremity ll) close tothe opposite inncr wall thcrcol' below its upper edge. The thread when pulled down into the tube or lining .lli passes under the pin and is thereafter held by it 'l'rom escaping, as a forwardly thrown thrcznl-loop will drop across in this embodiment of my invention the diversion or change in the direction of the thread in'iparls the requisite drag or tension thereto, as in the first i'orm illustrated.

ln the modification shown in Figs. 11 and 12, a so-cal|cd lc 'l't-haialcd shuttle is shown: and the transverse thread passage it) to its h-mgiliulinal center, being intersected by two vertical holes 21. 22 bored 'l'rom the shuttle bottom upward. lliich one of the holes receives one of the reiaining devices shown scparately in Fig. 8, as clearly shown in Fig. 12. the bodies 6 being held tightly in said holes while the hook-like hads T are E concentric and in the passage .20. with their entrances opposite the igitersection of the inclined slot 2?; with the passage 20, said slot. 23 and the intersecting vertical slot. 24; constitnting an open threading-slot. l he shut:- t-le body is vertically recessed fron'i its top at to form a receiving thread passage, leading from the bobbin-recess I" to and comn'nniicating with the transverse, delivering thread passage 20, and also connn mieating at the enlarged forward end it, with the vertical slot J-l. i\ diagonal retaining pin 27 crosses the passage and projects into an ol'l'sct 2H lliercoi. to permit the thread to pass easily down and underneath said pin but thereafter preventing its escape 'l'roni the passage .25. in the bottom oi whi h a tension pa'd 2t) of felt or other suitable material is secured.

The threading operation will be a pparent, the thr ad being drawn by the weaver into the slots 2st, 23 constituting the open threading-slot and being guided thereby into the passage beneath the retaining pin li, the thread as it. leaves the inclined slot 2 entering the heads 7 arranged side by side in the thread passage 20. Said hook-like heads not only retain the thread in the transverse passage 20 but. also serve as a metallic lining tliere'lor, as the thread is supported by the two heads and the upper edges of the bodies (3 upon which they are mounted, giving a free delivery o'l the thread while at the same time eli'ectually controlling it to prevent escape thereof from the dclivcring pr age.
